we are having  105 DUPLICATE/CNF computer objects. Something about how systems are being joined is triggering that. CNF object means the same object was created on separate DCs close to the same time. Then when replication happens they conflict, and one wins, and one becomes a CNF object. Usually the CNF one can be deleted. This doesn't tend to come from QAS. Maybe if someone ran vastool join twice in a row, and vastool picked a different DC for the two, that could trigger it, but unlikely.

 we are getting this CNF objects when we join unix server to the domain through vas deployment tool.

 any ideas as to why CNF objects are being created in AD?

I apologize.  I think this is a verbatim asking of a question asked late last week which didn't get any responses.  Unfortunately, I fear the content of the question which didn't get responses hasn't changed.  :-/  Lets try a few questions and suggestions which might help, but I'll preface it the caveat that I don't know exactly what is going on.

First, what is QAS?  Is that your machine provisioning software?  I assume 'vastool' and 'QAS' are related?  Can you provide more information?

Does vastool/QAS have logs to let you know exactly what they are doing?

I don't know vastool... but if it's unlikely that it's been run twice in a row... what might be more likely is that 'vastool' is running, but doesn't get a response it expected fast enough and tries a second domain controller?

vastool/qas are same  Its a tool which help for Centralize authentication.

even I buy your answer  that it tries a second DC, so how CNF objects are craeted

so trying to create computer objects in same container in 2 different sites at same time?

Where the value of 'same time' < 'speed of replication between domain controllers', yes.

can we delete the duplicate entry from AD side? Will it impact anything on current functionality
pramod1Author Commented:
but when we join the unix server we join at the domain, so how we will find which dc is it is hitting into.

The "CNF" objects shouldn't be in use, so they should be safe to remove.  It'd be nice to know exactly what's causing them though...

I would hope it would be recorded on the Unix server... but you should also be able to look at the computer object in AD and see where each was created.  Alternately, if you have the appropriate level of logging on the DCs, the security log will also record when and which server the computer objects were created.

what should i check in security log , like any key words to search?

I'd search for EventID 4741 on each of your domain controllers, but it is going to require that your domain controllers be configured to record those events in their logs.
